A frequency of 3 Hz implies that there are 3 cycles per second.

Frequency is defined as the number of cycles or oscillations per unit time. The SI unit of frequency is Hertz (Hz), where 1 Hz equals 1 cycle per second.

In the context of alternating current (AC), one cycle represents a complete sequence of changes in voltage or current from zero to maximum positive, back to zero, to maximum negative, and back to zero again. A frequency of 3 Hz means this complete cycle repeats 3 times every second.
